OK. Thank you so much for all your help, and sorry for troubling you so much. I think I have also tried manually. But still I am not able to ping from host. I followed the below steps. 1) rtnet stop = > since the rtnet driver was already loaded from boot. 2) modprobe -r e1000 (remove non-rt driver) 3) modprobe rtnet 4) modprobe rt_e1000 5) rtifconfig rtlo up 127.0.0.1 6) rtifconfig rteth0 up 192.168.56.101 After this only vnic0 is visible in ifconfig (with IP address). After that I also did: 7) ifconfig rtlo up 8) ifconfig rteth0 up Now, rtlo and rteth0 is visible, but I could not ping the IP from outside. Also, if I ping 192.168.56.101 locally also, it still returns 127.0.0.1 So, I tried changing the route, but no success. If any steps is missed out please let me know. Tomorrow, I will also cross check with init_inet() and update.
